Yeah, I get that you need to cross them to get the perpendicular vector of the surface. Basically, the surface integral eq in full form is ∫∫S F ⋅ (rs x rt)/|(rs x rt)| *(rs x rt) dA and for Gauss's Law it is ∫∫S E⋅n/|n| dA so you can see in the first one it simplifies to the cross product as...

When I learned Integrals in Calc III, the formula looked like this ∫∫ F(r(s,t))⋅(rs x rt)*dA but in physics for Gauss's law it is ∫∫E⋅nhat dA How are these the same basic formula? I know that nhat is a unit vector, so it is n/|n|, but in the actual equation, it is a dot between the cross...
